SELF-STABILIZED HOLOGRAPHIC RECORDING IN LINBO3-FE CRYSTALS

We describe the self-stabilized holographic recording in Fe-doped LiNb O3 crystals reaching almost 100% diffraction efficiency using weak int erfering beams of 514.5 nm wavelength, even for relatively low light p attern modulation values. The evolution of the recording process is sh own to be adequately described by a simple mathematical formulation ba sed on Kogelnik's coupled-wave theory in spite of the dynamic nature o f the recording process. Crystal parameters computed from this experim ent are compared to the available data from literature.
